\ GAS CONTROL.

Application filed August 17, 1926. Serial No. 129,764.

This invention relates to devices for con-- trolling the flow of gasfrom the terminals within a wall.

One of the objects of this invention is to provide a valve or cock that can be manipulated by the end of a gas hose inserted through an opening in a wall.

Another. object is to provide an indicating plate yieldingly interconnected with the gas cock by which the position of the gas cock may be ascertained when the gas hose is removed, adapted to yield when the gas-hose is slipped over the cock. I

Another object is to provide a cover plate by whichthe yielding indicating plate is held in place within the wall, so that the gas cock is also covered up and inclosed except for the front end protruding from the wall through this cover plate.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in which- Fig. 1 is a fragmentary general midsectional view of an enclosure for a gas pipe terminal, having a gas cock in proper position and provided with indicating and covering means embodying this invention.

, Fig. 2 is a front elevation of the cover plate illustrating the indicating plate in proper position behind the opening of the cover plate over the front end of the cock.

Fig. 3 is a cross section through the gas cook on line 33 of Fig. 1.

Gas cocks protruding fully from the wall of a house are subject to the risk that children may meddle with them.

It is therefore desirable to enclose such gas cocks in the wall. Atthe same time it is desirable that such a structure be as simple as possible without requiring special hose connections. 1

As illustrated in the drawing, the nipple end 4: of the cock 5 is of the customary plain grooved type over which the rubber nipple of a gas hose may he slipped. The gas cock in this case, however, is provided with a central bore 6 in conjunction with a cross bore 7 to communicate and align with a longitudinal bore 8 in the plug 9 when the cock is opened. The plug 9 is threadedly engaged with the terminal 10 of a gas pipe, as indicated at 11. The plug 9 is provided with a conical bore 12 for the gas cock 5 and also with the bore 8, referred to above, parallel and adjacent to the conical bore. The spring 18 in conjunction with pin lat serves to hold the cock 5 seated within the plug 9.

The whole structure of the pipe terminal 10 with the plug 9 and the cock 5 is disposed within a recess of a wall 15 with a front nipple l of the gas cock preferably to a small extent or not at all protruding'froi'n the wall.

A gas cock of' this type can easily be turned by means of a gas hose, slipped with its rubber end nipple over the gas cock nipple 4.. A cover plate 16 is provided to close the front end of the'recess 17 in the wall. This cover plate is provided with an opening 18 of a suitably large size in order to facilitate the a'm'ilying of a rubber end of a gas hose. The hole, 18 is preferably large enough to allow an insertion of a gas-hose to abut against a yielding indicating plate 19. This yielding plate is suitably larger than the opening 18 in order to be kept within the wall recess 17 by the cover plate 16. A spring 20 is inserted between the plug 9 and the yielding indicating plate 19, by which the indicating plate is yieldingly held against the cover plate 16. The spring 20 is preferably wound in hexagonal spirals to engage over the hexagonal portion 21 of the gas cock, in order to transmit any turning motion of the gas cock to the indicating plate 19. An indicating mark 22 is provided on the indicating plate to come into an alignment with certain indicatio s 23 or 24 on the cover plate. depending on the position of the gas cock.

In Fig. 1 a portion of a rubber nipple 28 of agas hose is illustrated in engaging posit-ion on the nipple l. disposed through the hole 18 in the cover plate 16, with its front end pressing against the indicating plate 19, so that this indicating plate is pressed 1nwardly away from the cover plate. When the hose is removed from the nipple the indicating plate 19 takes the position indicated in dotted lines at 25 directly behind the cover plate 16. thereby giving a neat closed appearance around the centrally disposed nipple 4:, the front end of the nipple merely protruding from the indicating plate 19 1n such an inoperative position.

A packing or sealing washer 26 is dis posed between the termination of the gas pipe 10 and the plug 9, the seahng washer being of a size to seal the recess 17 from the outside by being firmly inclosed by tube ex- Jill tension 27 from the rear of the cover plate 16,

Having thus described my invention, I claim:

I]. A LZISCOIIUOl comprising, in combination with a gas suppl pipe embedded in a all with the end of the pipe terminating within a recess of the wall, a gas-cock with connecting; nipple longitudinally disposed in the end of said pipe and so as to protrude from said recess. a eovenplatie disposed over said recess and having: an opening through which a gas host: may he applied over said nip ile. and an indicating plate of a size to close said opening FY0111 the rear of. the cover plate and operativelv and lQlCllllQ'lj. conneeted to the said cock to indicate the position of the cock through the opening when the hose removed.

2. A gaseontrol comprising, in combination with a gas supply pipe embedded in a wall with the end of the pipe terminating within a recess of the wall, a gas-cool; with con net-ting; nipple longitudinally disposed in the end oi? said pipe and so as to protrude lroin said recess. a cover-plate disposed over said recess and having an opening;- through which a as hose may he applied over said nipple and having: indicating means on its outside lace, and an indicating plate operati\'el and yieldingly connected to the said cock to he rotated with the cock and having means to align with the indicating means on the (JOVtPlJltllTk for indicating the position of the coelr.

ii. A ras control comprising. in combination with a supply pipe embedded in a wall with the end of the pipe terminating within a recess of the wall, a gas-cock with connecting: nipple longitudinally disposed in the end of said pipe and so as to protrude from said recess, a cover-plate disposed over eases? said recess and having an opening through which a gas hose may be applied over said nipple and having indicating means on its outer face, an indi rating plate of a size to close said opening from the rear and having indicating means on its front face to align with the indicating means on the cover-plate, the said cock ha ving means to support a con necting member and a spring operatively cagag ed with said support means of the cook to he rotated with the cool; and hciua' also operatirely connected to the indicating; plate to transn'iit the rotating movements ol the cool; to the indicating plai the spring serving also to hold the indicating plate against the rear oi the covenplate when no hose is on the nipple oi the cock so as to close the ()iimlllllg of the cover-plate and adapted to yield when the nipple of a hose is slipped over the nipple oi? the cock.

i. A gaseontrol comprising, in comhination with a supply pipe embedded in a wall with the end of the pipe terminating within a recess of the wall, a ens-cool: with connecting nipple longitudinally disposed in the end of said pipe, a cover-} latie disposed over said recess and having an, opening through which a gas hose may he applied over said nipple and having a tubular incinher extending from the rear of the coverplate into said recess around said pipe end, sealing means between the said pipe end and the tubular member to prevent an escape of gas from the cock into the wall, and an iudicatiin; plate operatively supported by the gas-cook and adapted to close said opening around said nipple oi the cock.

In testimony that I claim the foregoing as my invention I have signed in name.
